crust

the outermost part of the lithosphere, either oceanic or continental

oceanic crust

the portion of Earth's crust that is usually below the oceans and not associated with continental areas, thinner and higher in density than continental crust and basaltic rather than granitic in composition

inner core

A dense sphere of solid iron and nickel at the center of Earth; under the most pressure, it does NOT move

lithosphere

A rigid layer made up of the uppermost part of the mantle and the crust.

movement of outer core responsible for

Earth's changing magnetic field

Layers of the earth from the inside out

Inner core, outer core, mesosphere, asthenosphere, and lithosphere

Mantle

Largest layer of the earth; made up of liquid and solid magma

As you go deeper into the Earth

Temperature and pressure increase

continental crust

The portion of the earth's crust that primarily contains granite, is less dense than oceanic crust but is thicker

convection

The transfer of heat by the movement of a fluid or gas in a current

three main layers of the Earth

crust, mantle, core

powers a convection current

heating and cooling, changes in density, and the force of gravity

outer core

moves because it is liquid/molten metal (iron and nickel)

seismic waves

produced by Earthquakes; helps geologists indirectly learn about Earth's interior
